He told Hello! Magazine: "We only really decided to move back when we got back."

The couple, who married in Tuscany in September, lived in Sydney for two years - though Vogue admits she missed her family.

"I've never met anybody who has so many close friends," said Brian. "I think she was probably getting a bit edgy in Australia, just being the two of us."

Brian decided to release a new album and tour again after supporting his mentor Ronan Keating this year.

He said: "It was my first time touring in eight years and I didn't know how it was going to be. When I got such a good response after the first few gigs, I thought if ever I was going to come back and put an album out and do a tour, this was obviously the time."

Vogue, 27, said they would like to start a family. Brian has two daughters Molly, 11, and Lilly, 10, from his first marriage. She said: "I don't feel I'm in any rush, but it's one of the reasons I wanted to make a base here. I think 30 would be a good age - I still have lots of things I want to achieve."

Brian said: "I'd like to see Vogue concentrate on her career. I'd be happy to be a stay-at-home dad."
